AquascapeAlgaecide for Ponds, Waterfalls, and Fountains – Fast-Acting Algae Control, 32 oz / 946 ml, 96024

Worked great algae gone

I had some reservations about purchasing this with "so-so" reviews. Have a (9 gal) stone garden fountain with a String Algae issue. My fountain incorporates simple water plants and naturally growing mosses (no fish). Concerned about plants and mosses being exposed to an algaecide. So with caution I dosed sparingly (1/2 strength) every other day. 6th day conspicuous improvement. String Algae dying and dead, BUT plants and mosses unaffected👍! I maintain my 'sweet-spot' dose upon every water added topping off. Dead pieces of algae have to be removed manually (adios!) Be PATIENT. Go slow when other plant forms are involved. (No fish here, so cannot advise🙏)

Keeps the algae away.

The media could not be loaded. Before using this product, the rocks in my small outdoor fountains always ended up with a layer of green slime that needed to be scrubbed off at the end of the season.I was wary of using ANY product in the fountains because birds, squirrels, and even raccoons drink from them. I took a chance with this, and it payed off. Nearby plants aren’t harmed, wildlife is unaffected, and no more slime buildup. I retreat the fountains every 3-4 weeks because I top off the fountains with water every day throughout the summer.

Careful when using this. All algicides will raise the pH but so far I like this one best. It gets rid of algae fast so always use as little as possible, I actually use half doses with pH down to get rid of it slowly. Good value, packaged well didn't leak arrived fast.

If I could give negative stars I would. The video for this product shows a woman putting it into her Koi pond which gives the illusion it is safe for Koi. It also states in its advertising to be safe for fish and plants. This product almost killed my entire Koi pond. I spent 16 hours emptying my pond in a panic because all of my fish were gasping for air, I have a 5000 gallon Koi pond with plenty of aeration as well as a large waterfall . I spoke to numerous specialist, who all told me this product should be taken off the market as it is poison. It has misleading claims and misleading advertising. I can’t stress enough not to buy this product. In addition to killing 2 baby fish, it also killed plants in my pond.This product needs to be taken off the market!!! I cannot stress enough, not to buy this product.

Bought it because it claimed not to harm fish, I don't have fish but wanted to protect frogs living in the pond. I don't think it's strong enough to kill string algea.

Even though it doesn't work so well in cold weather it still does it's job. I have an approximate 4500 Gal. Pond and have a waterfall pump and filter and a separate pump aerating the water and they are running 24/7. Placing this in the water every 3 days until pond is clear from this green water single cell algae, is slowly doing it's job. Have been finding small clumps of algae and the water in the pond ie beginning to clear up. Have been using this product for 3 weeks now but water is still green, beginning to see the Koi. It works, but slower than I thought it would.3/3/22 Been using this for a month now, since it's been cold in Orange County, it's working a little slow, but it is working. When I first started using this, I couldn't see our Koi, now I can see them below the surface. Water is still not clear of green water algae, but it's getting there. The submersible pump I'm using to aerate water more is always getting clogged with algae clumps so I know the product is working. Hopefully, won't be too much longer before the green water algae is gone?
